Exploded Bee Nests/Beehives don't releases Bees and don't keep them inside the block

Put a Bee Nest or a Beehive near some flowers and spawn some Bees and wait them to enter it it. When there's a bee inside it, put a TNT and activate it. The Bee Nest will disapper totally and the Beehive will drop, but in neither cases Bees will be released and if you put the Beehive back, there will be no Bees inside it
